ROLLER CHAIN FOR SILK DRIER-S.

Application filed October 3, 1925.

My invention relates to certain improvements in chain conveyors for driers, and especially those used in drying silk. In this type of drier, roller chains are used, which support the poles upon which the silk is hung.

One object of my invention is to provide the chains with cushions, on which the poles are mounted, and to make the cushions removable so that they can be replaced when worn. V

In the accompanying drawings:

l is a side view'of one side of a roller chain illustrating my invention;

Fig. 2 is a plan View;

Fig. 4 is a transverse sectional view on the line H, Fig. 1;

Fig. 5 is a transverse sectional view on the line 55, Fig. 1;

Fig. 6 is a detached perspective view of the cushion; and

Fig. 7 is a sectional perspective view illustrating a portion of the cushion.

The chain is made of two series of links 1 and 2, spaced apart as shown. The ends of one pair of links are coupled to the ends of an adjoining pair of links by'pivot pins 3. On one end of each pair of links are internal bosses, through which the pins extend and on which are mounted rollers 4.

The rollers travel on a track 5, which is angular in form, the vertical member of the angle limiting the lateral movement of the chain in one direction, and a lighter angle rail 6 extending on the opposite side of the chain limiting the lateral movement of the chain in the opposite direction.

In order to prevent the chain tilting laterally, some of the pivot pins 3 are extended, as in Fig. 1, and rollers 7 are mounted on the extensions of the pivot pins outside of the chain. A rail 8, angular in crosssection, extends over the rollers 7, as in Figs. 3 and i, as the rollers travel on the track 5. In the present instance, each alternate pin. is extended and -is provided with one of the rollers 7.

Serial No. 60,242.

The upper surface of each link 1 has two sockets 9 for the poles 10 which carry the si k or other material to be dried. The other links 2- are higher than the sockets, and act to prevent longitudinal movement of the poles on the links.

The poles of the silk drier are preferably enameled, or made of wood, and their surface must be smooth to prevent the silk from catching on the pole, In order to protect the poles, a detachable cushion 11 is provided, which is shaped to conform to the sockets 9 in the links.

This cushion is preferably made of a tubular fabric 12, through which extends a flat metallic core 13, shaped to lit the sockets and turned under the end projections 14 of the links, as shown in Fig. 1. This construction holds the ends of the cushion in place. A screw-bolt 15 extends through the center of the cushion and into an opening on the link. On the bolt is a nut 16, which secures the center of the cushion to the link. On removing the screwbolt, the cushion can be detached from the link when worn, and a new cushion substituted for it.

I claim:

1. The combination of a conyevor chain made of a series of links, said links having sockets for poles; and a cushion for the sockets, said cushion having a metallic core shaped to conform to the upper surface of the link turned under each. end of the link; and a fabric covering enclosing the core.

2. The combination of a link of a conveyor chain having two sockets for poles; a cushion strip shaped to fit the two sockets, and means for attaching the strip to the link between the two sockets.

3. The combination of a link of a conveyor chain having two sockets for poles and end projections; a cushion strip having a core of flexible material and a fabric covering; and a bolt securing the cushion strip to the center of the link between the two sockets, said strip being turned under the end projections of the link.
